  • Patent number: 12253587
    Abstract: The present disclosure provides transmit/receive (T/R) systems for NMR or MRI systems. In one configuration, the systems and methods provided herein may use passively-shielded coils that are compatible with low-field operational environment to replace conventional T/R systems and spatial gradient systems. In some configurations, a low-field imaging T/R system is provided that is designed for nuclear magnetic stimulation and local flux sensitivity, while automatically rejecting incident radiant electromagnetic noise. The design advantageously leverages low required frequencies to distribute the pulse synthesis task, yielding a smaller system with easier maintenance and lower cost. The system may include distributed coil nodes that include a primary radiofrequency (RF) coil configured to transmit and receive RF signals and a secondary coil configured to passively shield the primary RF coil.
